Business Loop I-90 - Gillette
Business Loop I-90, U.S. 14-16 and WYO 59 shield assembly west of Downtown Gillette, Wyoming. Photo by Joe Kohler (2000). Older state highway shields in Wyoming used brown lettering and numbering instead of black. Over time these were phased out.
Business Loop I-90 overlaps with U.S. 14 & 16 along 2nd Street through the Gillette city center. The business route separates from I-90 at the diamond interchange (Exit 124) with Wyoming 50 (Skyline Drive) in west Gillette. Skyline Drive in turn links the freeway with adjacent U.S. 14 & 16 and Wyoming 59 to the north. Wyoming 59 accompanies the three routes east through Downtown to Douglas Highway south. Business Loop I-90 ends where U.S. 14 & 16 join I-90 east to Moorcroft at Exit 128.
